can they actually fix the problem properly?

they can, but it seems like even when they replace the HPFP, LPFP, and all the component the N54 engine continues to have the same issues. I believe BMW has acknowledged this by abandoning the n54 engine in the F10s for a more reliable single turbo, twin screw setup.

Damn, what a disappointment. I love this car. Any advice on what i should tell the dealership when I go in on Monday? I just want to get this issue resolved. BTW, is there a time period for the lemon law effect?

i had my vehicle for close to a year and half before i lemoned my car. my attorney's were able to get bmwna to settle within a week after submitting the court docs.

as for the dealership, just tell the SA that your vehicle is having a delayed reaction when you start the vehicle. Make sure you tell them it is HPFP related.

Be sure to check the lemon laws for your particular state if thats the route you are going to go. Each state has different policies on lemons. Usually the vehicle has to have the same defect/problem within a certain timeframe. The other is if the dealer has the vehicle for a certian period of time trying to repair the problem and is still unable to fix it. However, for peace of mind, yes bring it to the dealer and see what they can find. I used to be a BMW tech, and in my experience, letting the vehicle sit for extended periods did cause a rough/delayed start. However, without physically seeing/driving the car, I can't make a clear cut diagnosis.

I will be bringing in my car for service monday. I just want the problem fixed. Not trying to return my car at all. Paulie, is it unusual if I get a delayed start like 3x a week in the winter time from the cold weather? The delayed start didn't happen in the summer time. Thanks for your input

is the delayed start when you start it first thing in the morning? or does it do it throughout the day? 1st time in the morning, not all that unusual. But if it is doing it even when the engine is warmed up, it could be an indicator of a progressing problem

Only in the morning. Not throughout the day. I'm going to get it checked out on monday. Thanks for all your help guys.

1st start in the morning especially in cold temps can cause a slight delay before the engine fires up. the fuel mixture has to be slightly richer when cold to get fired up. doesn't hurt to have it checked though

what are some symptoms of a HPFP failure?
